Problem the AI is intended to solve

A deep learning model is being trained using a subset of meteorological forcings and remote sensing observations of snow cover to reconstruct seasonal snow water content globally. The relatively small quantity and location-independent model inputs mean that the model is transferrable globally with little computational cost.

Expected benefits

Deep learning model outputs are being assimilated with NASA process based hydrologic models. This will provide the capability to bias correct for common model errors that are driving snow-fed hydrologic biases in operationally used NASA products.

System outputs

Global, daily, and 1km-resolution SWE, and SWE uncertainty
